Construction on the Highway 101: Montecito and Santa Barbara South segments shifts to the southbound side, the Santa Barbara County Association of Governments (SBCAG) reports

On Saturday night, July 12, the southbound freeway traffic will move to the median and be divided by safety barriers from Olive Mill Road to Posilipo Lane.

The southbound on-ramps at Olive Mill Road and at San Ysidro Road will close for construction that night.

This follows the June 28 opening of reconstructed northbound lanes between Sheffield Drive and Hermosillo Road; a new northbound auxiliary lane between San Ysidro and Olive Mill Roads; an upgraded northbound on-ramp at San Ysidro Road; and an updated off-ramp at Hermosillo Road.

The southbound divided lanes enable crews to build new freeway lanes while keeping two lanes open for the traveling public during the day and protecting the bridge over-crossings at San Ysidro and Olive Mill Roads, SBCAG said.

The southbound on-ramp at Olive Mill Road will be closed for nine months for construction, and drivers can use a detour along North Jameson Lane to access the southbound on-ramp at Sheffield Drive.

The southbound off-ramp at San Ysidro Road will close for three months, and drivers can use the southbound off-ramp at Sheffield Drive as a detour.

Now open on northbound Highway 101 are: two improved freeway lanes between Sheffield Drive and Hermosillo Road; a new auxiliary lane; updated on- and off-ramps at San Ysidro Road; enhanced off-ramps at Olive Mill and Hermosillo roads; drainage improvements; and new, wider bridge segments at Romero, San Ysidro, and Oak Creeks.

The northbound auxiliary lane improves merging for drivers entering and exiting the freeway between San Ysidro and Olive Mill Roads, SBCAG said.
